When the Saints traded away their second-round pick in next year's draft to select running back Alvin Kamara in the third round of this year's draft, many shook their heads in confusion.

That's because the Saints already had Mark Ingram, who rushed for over 1,000 yards last year, and had just signed Adrian Peterson in free agency.

Kamara proved early in Sunday's preseason game against the Chargers, taking their first play from scrimmage to the house for a 50-yard touchdown, that the Saints may have known what they were doing after all.

Kamara will remind many Saints fans of Darren Sproles and Reggie Bush. While he's built a little more like Bush than Sproles, his route running and rushing style seem to resemble Sproles'.

The Saints can be a nightmare for fantasy football owners. With a number of wide receivers, tight ends and running backs targeted by Drew Brees week in and week out, it is hard to trust anyone on a weekly basis. But Kamara could be a PPR hero this season.

Last year, New Orleans used Travaris Cadet as their pass-catching back, but he didn't quite show the same elusiveness as some of the Saints' more successful players who had previously occupied that role.

Kamara will likely line up in the backfield and the slot this season, and he also returned punts Sunday night. He could be among the highest-scoring rookie running backs in a number of formats this season if Sunday's outburst was any indication of his role in the Saints' offense.
